Dies ist vor allem für die Anwendung von PEF auf Objekten mit Betriebstemperaturen von - 50 °C bis - 80 °C von Bedeutung. Die Spannung sollte auf ein Mindestmaß beschränkt bleiben, indem der Schaum "unter Druck" angewandt wird, d. h. indem die Teile großzügig zugeschnitten werden. In jedem Fall sollten die Empfehlungen des Herstellers beachtet werden.
Die Produkte werden in der Form von Schläuchen, Profilen, Platten, Rollen und Bändern mit oder ohne Beschichtung und/oder selbstklebende Trägerschicht und/oder verschiedene Verschlusssysteme hergestellt.
Dieses Dokument beschreibt die Stoffeigenschaften und enthält die Prüfverfahren und Festlegungen für die Konformitätsbewertung, die Kennzeichnung und die Etikettierung.
In diesem Dokument beschriebene Produkte werden auch in vorgefertigten Wärmedämmsystemen und Mehrschicht-Verbundplatten angewendet; die Eigenschaften von Systemen, in die diese Produkte integriert sind, werden nicht behandelt.
Dieses Dokument legt keine Leistungsstufen für eine vorgegebene Eigenschaft fest, die ein Produkt erreichen muss, um für einen bestimmten Anwendungsfall tauglich zu sein. Für bestimmte Anwendungen benötigte Anforderungen können Regelwerken oder übereinstimmenden Normen entnommen werden.
Dieses Dokument gilt nicht für Produkte, deren Nennwert der Wärmeleitfähigkeit größer ist als 0,050 W/(m×K) bei 10 °C.
Dieses Dokument gilt nicht für Produkte, die zur Dämmung von Gebäudehüllen bestimmt sind.
Unter üblichen Bedingungen unterliegen Produkte aus Polyethylenschaum keiner Druckspannung (siehe D.2). Deshalb wird diese Eigenschaft nicht im normativen Teil dieser Norm behandelt.

1 Scope This European Standard specifies the requirements for factory made flexible polyethylene foam products which are used for the thermal insulation of building equipment and industrial installations with an operating tempera-ture in the range of approximately - 80 °C to + 150 °C. NOTE Tensile stress in the insulation product should be avoided when applying PEF. This is even more important when applying PEF on lines with operating temperatures between - 50 °C and - 80 °C. The tensile stress should be kept at the minimum by applying the foam “under pressure”, i.e. cutting the parts in a generous way. Manufacturer’s advice should be heeded in all cases. The products are manufactured in the form of tubes, profiles, sheets, rolls and tapes with or without coating and/or self-adhesive backing and/or different closure systems. This standard describes product characteristics and includes procedures for testing, evaluation of conformity, marking and labelling. Products covered by this standard are also used in prefabricated thermal insulation systems and composite panels; the performance of systems incorporating these products is not covered. This standard does not specify the required level of a given property that shall be achieved by a product to demonstrate fitness for purpose in a particular application. The levels required for a given application can be found in regulations and invitations to tender. Products with a declared thermal conductivity greater than 0,050 W/(m·K) at 10 °C are not covered by this standard. This standard does not cover products for the insulation of the building structure. The normative part of this standard does not cover compressive stress (see Annex C, C.4). 2 Normative references The following referenced documents are indispensable for the application of this document.

At the maximum service temperature, ST(+), the mean value of relative change in thickness (reduction), ∆εd, shall not exceed 7 %. The maximum service temperature, ST(+), shall be declared below 100 °C in steps of not less than 5 °C and above 100 °C in steps of not less than 10 °C. SIST EN 14313:2010
EN 14313:2009 (E) 13 4.3.3 Minimum service temperature The manufacturer of an insulation material can choose which minimum service temperature he intends to de-clare for his product. This minimum service temperature does not represent any specific physical property and cannot be deter-mined by any single standardized test method.
If a minimum service temperature is declared by the manufacturer the following physical properties in line with European test standards have to be declared at the declared minimum service temperature:
a) Thermal conductivity as a function of temperature;
b) Coefficient of thermal expansion as a function of temperature (see Annex B); c) Tensile strength and/or compressive strength and Young's modulus as a function of temperature as agreed between the parties.
In addition, other physical properties may be agreed upon by the concerned parties.
Using these temperature dependent physical data, the suitability of any specific insulation can be estimated at a given low operational temperature for industrial installations in relation to application related design features.
A low operational temperature cannot be below the minimum service temperature. The minimum service temperature, ST(–), shall be declared in levels with steps of 10 °C. Minimum service temperature within the scope of this standard but above 0 °C need not be tested. 4.3.4 Water absorption Short-term water absorption by partial immersion, Wp, shall be determined in accordance with EN 1609 for flat products or EN 13472 for tubes (method B = drainage). Tests shall be run with specimens of ≥ 15 mm thick-ness from one sample each being representa
